Get NMEA message meta data.

Parameters

[out]	meta	The meta data
[in]	msg	Pointer to the NMEA message
[in]	msg_size	Size of the NMEA message (>= 11)

Note: No check on the data provided is done. The caller must ensure that the data is a correct NMEA message.

Parameters

[out]	name	String to write the name to
[in]	size	Size of `name` (incl. nul termination)
[in]	msg	Pointer to the NMEA message
[in]	msg_size	Size of the `msg`

Note: No check on the data provided is done. The caller must ensure that the data is a valid NMEA message.
